When I do up my detector guide I have to weigh detectors myself to get real world weights including batteries. The only weight that matters is what is on your arm, and excluding battery weight gives a false idea the detector is lighter than it is in actuality. The detector ships with four alkaline C cells and weight should be quoted with them in the detector. Four each Energizer alkaline C cells weigh 9.46 ounces or 0.6 lbs giving a total weight of 5.9 lbs.Steve's very personal detector weight conversion chart: Under 3.0 pounds equals Very Light Weight Detector 3.0 - 3.99 equals Light Weight Detector 4.0 - 4.99 equals Medium Weight Detector 5.0 - 5.99 equals Heavy Metal Detector 6.0 - 6.99 equals Very Heavy Metal Detector For reference a GPX 5000 on arm is 5.3 pounds (battery on back and so not counted) and Garrett ATX is 6.9 lbs.

The basic pulse induction detector sends a pulse of current through a coil in the search head. At the end of the pulse the current is shut off. Once a current is running it does not like to stop suddenly and there is a "boomerang effect" that briefly induces a very large voltage spike across the coil. Once this transient spike dissipates, the detector can go into receive mode. The intentional portion is referred to as the "transmit pulse" and the follow up spike the "flyback pulse". There are different ways of looking at the situation but in most cases the flyback pulse is viewed as a problem to be dealt with. The sooner the detector can receive or "sample" the better it is at detecting quickly disappearing signals from small gold. The whole MPF thing is just another acronym for our collection referring to Minelabs method of dealing with the flyback pulse and achieving greater sensitivity to small gold. Whether it is SD based or GP based is all rather beside the point. All that matters is how it works in the field. I expected you to come out swinging harder on the price Rick. On other forums you have stated the SDC 2300 is "DOA" at certain price levels. How do you account for the GPX being the most expensive consumer detector sold and yet sold in huge numbers world-wide? I am not arguing with you though and indeed please voice your opinion on the subject. Until the unit is actually on the market Minelab has time to gauge responses and set the price wherever they want. You have a very valid point on the SDC versus ATX for the price and what they offer. I think you are missing something though. The SDC is not bring priced against the Garrett ATX. It is being priced against a GPX 5000 and will be marketed world wide to people who will not consider anything that does not say Minelab on it. The SDC is compact, waterproof, simple to operate, and most importantly, runs on regular batteries. At two thirds the price of a GPX if they can get just a few Africans to use it and find gold with it then they may have the next hot machine. The way things work over there defy normal marketing beliefs and ideas.
